HAY-CARRIER.

Specification of Letters Patent.

Application filed August 16, 1905.

Patented March 10,1908.

serial No. 274,374.

To all whom t may concern: l

Be it known that I, RICHARD MILLER, residing in Appleton, in the countyof Outagamie and State of Wisconsin, have invented new and usefulImprovements in Hay-Carriers, of which the following is a description,reference being had to the accompanying drawings, which are a part ofthis specification.

My invention has relation to improvements in hay carriers, andparticularly to the mechanism for raising and lowering the load, andholding said load in locked elevated position below the carriage.

The primary object of the invention is to improve that portion of themechanism of the carrier which is employed for raising and lowering theload, whereby a construction is produced which is most effective inoperation, and whereby, also, simplicity is secured overconstructions'now in ordinary use.

A further important object of the invention is to provide an improvedconstruction whereby the lifting devices are drawn towards each otherand their inner ends made to automatically engage each other releasably,when draft is applied to the hoisting rope.

With the above object, and other incidental objects, in view, theinvention consists of the devices and parts, or their equivalents, ashereinafter set forth.

Referring to the drawings, Figure 1 is an elevation of my invention;Fig. 2 is a side elevation of the lifting devices, showing the same inthe position they would occupy before a pull is exerted-upwardly on thehoisting rope 3 is a plan view of Fig.-2; and

Fig. 4 is a view showing the inner ends of the lifting devices lockedreleasably together, and which occurs, when draft is applied to thehoisting load.

The improvements are designed to beused in connection with any improvedform of traveling carrier and allied parts, and may be found to workparticularly well in conjunction withl a traveling Vcarriage and relatedparts such as shown in my pending application for patent, forimprovements in hay carriers, filed May 12, 1905, Serial No. 260,201. Ihave, therefore, in Fig. 1 of the accompanying drawings, shown afragment of one of the parallel side plates of the supporting frame, andalso. one of the adjustable plates for the pivot bolt of the pivotallymounted member of the rope clamping mechanism, shown in my pendingapplication for patent aforesaid, the said fragment of the supportingplate, in the present application, being designated by the numeral 5,.the ad? justable plate referred to by the numeral 6, and the pivot boltby the numeral 7. I furthermore show the pair of pulleys mounted betweenthe supporting plates and designated by the numerals 8 and 9; one of thepivoted bell-crank levers, designated by the numeral 10; the swingingyoke designated by the numeral 11, having formed at its lower end thering designated by the numeral 12; the tubular cam lever designated bythe numeral 13, pivoted in the outstretched arms of the section 14 of alower rope clamp, whose other section 15 is adapted to be forced towardsection 14 by means of the cam shoulder of the cam lever and clamp thehoisting rope therebetween, the said sections 14 and 15 being providedat their u per ends with the flanges forming the iskshaped buer 16 toengage with the ring 12. All the arts mentioned are shown clearly in mysaid prior application for patent, but will, nevertheless be hereinafterreferred to brieiiy in explaining the operation of the presentinvention.

Referring particularly to the improvements, the numeral 17 indicates oneof the lifting devices for engaging the ropes of the hay slin (notshown). This lifting device is provi ed at its outer end with a hook,

which is shown, in Figs. 2 and 3, as in engagement with oneof the ropes18 of the hay sling. From its hooked outer end, this hook memberpreferably comprises two separated arms 19, 19 which are diverged for adesired i distance in a direction away from the hook, then run straightand parallel for a short distance, then inwardly and upwardly for alimited distance, and finally upwardly in parallel lines to formlugs 20,20 which are connected by means of a transverse bolt 21.

A substantially cup-like socket 22 is disposed between the arms 19, 19of the lifting device 17, and this cup-like socket has eX- tending fromopposite sides thereof and outwardly lugs 23, 23, which are secured bymeans of bolts 24, 24, to the substantially straight parallel portionsof the arms 19. The top of the cup-like socket is provided row slot 26extending inwardly therefrom.

Secured to the outside of the arms 19, preferably by means of the bolts24 which secure the cup-shaped socket in place, are inwardly extendingoutstanding 'brackets 27, 27. In these brackets are mounted the oppositeends of a fixed shaft 23, the said shaft also passing through o eningsin lugs 29, 29 extending downward y from the inner ends of arms 19, andthrough a sleeve 36 rejecting inwardly from the cup-shaped soc ret.Mounted revolubly upon the fixed shaft, in the spaces between thebrackets 27 and. the outer sides of the arms 19, are grooved pulleys 31and 32, respectively. The other lifting device is designated by thenumeral 33, and from its outer end inwardly this lifting device is inthe form of a yoke 34, with the arms of the yoke arranged one above theother, so that the space between said arms is disposed on a horizontalplane. The inner end of the yoke is formed with a series of indentationsor recesses separated by ridges 35, said ridges having their outer edgesof rounded convex contour. Projecting` from the extremity of this ridgedportion is a stud 36 terminating in a rounded head 37. Mountedhorizontally on a vertical axial pin 3S in the yoke opening is a pulley39. Extending transversely over the yoke 34, and secured by means of theaxial pin 38 is a looped rope guard 40. The lifting device 33 is shownin engagement with another of the hay sling ropes 41.

rlhe hoisting rope 42 enters at one end between the plates 5 of thesupportin T frame, and preferably over a small guide roller 43 at saidend of the frame, and is extended to and passes out over roller 9 at theother end, and then extends down and around pulley 32 of the liftingdevice 17, thence to and around pulley 39 of lifting device 33, thenceto and around the other pulley 31 of lifting device 17, thence upwardlyand over pulley 3, thence downwardly between the arms of the yoke 11,thence through the ring 12 and buffer 16, thence between the two members14 and 15 of the rope clamp, thence around the in 21 of the liftingdevice 17, thence upwardly to form a loop, its extremity beingadjustably connected to its downwardly extending portion by beingclamped within the tubular cam lever 13. The cam shoulder of the tubularcam lever is adapted to force the section 15 of the rope clamp towardthe other section of said clamp, to thereby 'clamp the hoisting rope 42therebetween, in the same manner as pointed out in my pendingapplication for atent herein before referred to. Also, as ful ydescribed in said pending application for patent, the rope clamp withits disk-shaped flange 16, forms an adjustable stop which may be raisedor lowered on the hoisting rope, when the cam lever 13 is in ahorizontal position, in order to lengthen or shorten the loop at the endof the hoisting rope, and when the desired adjustment obtained, it maybe rigidly clamped upon the hoisting rope by turning the cam lever 13 tothe position shown. During they hoisting operation, the movements of thehoisting rope will bring the buffer 16 into engagement with the ring 12,and thereby lift the horizontal arms of the bell-crank lever 1() (itbeing understood that two of these bell-crank levers are employed)causing them to swing. These bell-crank levers are employed to operateupon rope clamping mechanism rarried between the plates 5, but as thisclamping mechanism forms no part of the present invention, and is fullycovered in my pending application for patent herein before referred to,no detail illustration and description thereof are here deemednecessary.

Figs. 1, 2 and 3 show the hoistingr rop i and lifting devices in theirlowered positions and the hooked ends of said lifting devices are shownas in engagement with the ropes 13 and 41 of the hay sling. Draft is nowapplied on the hoisting rope, and as at this time the carriage is lockedin its position, such draft will serve to elevate the lifting devices 17and 33 and the load carried thereby. As the lifting devices are thuselevated their inner ends are drawn closer and closer together, the head37 of the stud 36 ol" the lil'ting device 33 Vnally seating itself inthe cupshaped socket 22, and with continued draft on the hoisting rope,the said head passes through the opening 25 and thence into the narrowslot 26, whereby the two parts of the lifting devices are automaticallylocked together, as clearly shown in Fig. 4, and said lifting devicescaused to assume the position shown in said Fig. 4. The rounded convexcontour of the head 37, and the rounded concavcd sha-pe of thecup-shaped socket compels the head 37 to pass through the opening 25.The rounded ridges 35 on the end of the yoke 34 form practically a ballbearing on the concave surface of the cup-shaped device, so as to permitturning of thc stud 36 in the slot 26 without excessive friction.

After the load is lifted, as above explained, the carriage is released,and consequently the draft on the hoisting rope will cause said carriageto move along the track. At the point of the discharge, the carriage isstopped in any suitable manner, and the load is released by uncouplingthe two sections of the hay sling, and said load allowed to drop withoutlowering the end of the hoisting rope, so that the return movement ofthe carriage to its loading position is made with the hoisting ropestill clamped in its raised position until the carriage is again locked,and the hoisting rope is then released and allowed to lower. After thelowering of the hoisting rope and the lifting devices in the mannerdescribed,

ltlt) the'said lifting devices if they had been previously recoupled aregrasped by hand and turned so that the stud 36 is brought into thevopening 25 of the cup-shaped device, when of course the two liftingdevices can beseparated and made to assume the position shown in Figs.1, 2 and 3, ready to again engage the ropes of the hay sling.

From the foregoing description, it will be seen that I provide acomparatively simple, but yet exceedingly effective lifting mechanismfor hay carriers, and also one in which the two lifting devicesautomatically couple together when a pull is exerted upwardly on thehoisting rope., l

I prefer to arrange the ulleys 31 and 32 of the lifting device 17 in t emanner clearly shown in the drawings, that is to say, upon the shaft 28,and in thespaces between the outstanding brackets 27, and the outersides of the arms 19. By this construction, and

by removing the nut on one end of the fixed' shaft 28, said shaft can bereadily drawn out of its bearings, and consequently the pulleys removed,so thatthe hoisting rope 42 is separated from the lifting device 17.This enables the lifting device 33 to be used independently of saidlifting device 17. In such case the hoisting rope is made to extendthrough the frame 5, thence over ulley 9, thence downwardly and aroundpul ey 39 of the lifting device 33, and thence upwardly and secured to adepending finger 44 from frame 5. Under this arrangement, the pulley 8would of course be idle, and the clamp 14-15 and cam 13 would also beomitted. Instead of the buffer 16 contacting with the ring 12, the head37 of the stud 36 would under this arrangement act to contact with thering 12 in order to operate the bell-crank levers. 10.
